1. Restart the PS4
When you get any type of error on PS4, the very first thing to try is to restart it. This will clear the RAM and cache memory from any bad files and give a new fresh start to the PS4 system. You need to completely turn off your PS4 and disconnect it from power.

What you have to do at this post is as follows:
- Turn off the PS4.
- Unplug the PS4 power cord from the wall power outlet or from the power strip.
- Unplug any peripheral connected to your PS4, including the controller and external HDD.
- Leave the console in this disconnection state for 3 minutes.
- Connect the PS4 to power, and connect the PS4 controller to it while other devices are still disconnected.
- Turn on the PS4 and wait for the system to get fully loaded.
- If your games are installed externally, connect the external HDD to the PS4 at this point.
Now, try to run your Call of Duty Warzone or Modern Warfare games and see whether this method has resolved the issue or not. If not, try the other methods below.
2. Move Your Games To the Internal HDD
In case you’re getting PS4 Error (CE-34878-0) when playing/launching Warzone or Modern Warfare from an external HDD, it’s strongly recommended that you move it to the local internal HDD of PS4.
3. Stay Up To Date
Make sure that your PS4 system software is up to date and so is your Warzone or Modern Warefare game. The PS4 Error (CE-34878-0) might be caused by file conflicts or incompatibility issues with the currently-installed PS4 system software version.
Updating the PS4 system software or the game itself might fix PS4 Error (CE-34878-0) as an update usually comes with bug fixes for common issues.
4. Reinstall the Game
The installation of your Warzone or Modern Warfare game might be corrupted or missing some core files. It’s wise in this situation to entirely delete the game and reinstall it from scratch.
If you’ve bought the digital copy of Warzone or Modern warfare and you’re going to download it from the Internet, make sure you have a stable and fast internet connection. We don’t recommend at all connecting to WiFi while downloading huge games.
On the other hand, if you own the disc copy of Warzone or Modern Warfare, make sure the disc is not scratched or dirty before reinstalling the game. It’s recommended to disconnect your console from the internet until the reinstallation process is complete.
5. Maintain Free Space On The PS4 Internal HDD
When the PS4 internal hard drive is full, errors may occur, and since Warzone and Modern Warfare games need lots of storage space to run properly, a shortage in space might cause serious data processing errors.
Therefore, free up your PS4 internal hard drive and keep at least 10% of the total available space FREE and unusable.
6. Rebuild the PS4 Database
One of the effective ways to fix the PS4 Error (CE-34878-0) on Call Of Duty Warzone and Modern Warfare is to rebuild the PS4 database, as that process has proven to resolve many performance issues in the PS4 system and eliminated different types of errors (read more).
We strongly recommend that you don’t rebuild the PS4 database until you move your Warzone or Modern Warfare to the internal HDD of PS4 in case they are installed externally.
Additionally, we also strongly recommend you rebuild the PS4 database if you’ve updated or reinstalled your games in pursuit to fix PS4 Error (CE-34878-0).
After you finish rebuilding the PS4 database, you need to restart your PS4 and check if this has fixed the PS4 Error (CE-34878-0) on Warzone or Modern Warfare.
7. Full Initialize the PS4
If nothing has worked for you to fix PS4 Error (CE-34878-0) on Warzone or Modern Warfare, you have to full initialize the PS4 and reinstall a new, clean copy of the PS4 system software from scratch. This process will eliminate any issue caused by missing/damaged system files.

Once this process is done, the very first game to install is the one that you have a problem with. Make sure the game is updated to the latest version as well.
8. Format the PS4 Internal HDD
This is the last resort before you contact PlayStation Support or the game developers. In many cases, fully formatting the PS4 internal hard drive has fixed serious errors in the PS4 system that nothing else could do. It’s because there might be some bad sectors on your PS4 hard drive that cause this data corruption/damage error in Warzone or Modern Warfare, and formatting will disable these bad sectors
and restore the original performance of the hard drive.
If you’re not tech-savvy, seek the assistance of one to help you pull out the PS4 internal HDD and connect it to a PC in order to format it.
9. Contact the Game Developers
There might be a bug in the game you’re playing that causes either a functionality issue in the game or an incompatibility issue with the currently-installed PS4 system software version.
